September Climate Summary

September Climate Summary for Northeast Florida and Southeast Georgia

The lack on any tropical cyclone activity in the local area led to fairly average weather conditions for the first month of fall across the region. Temperatures were slightly above normal with rainfall amounts generally slightly below normal. A few weakening frontal boundaries slipped southward into the forecast area during the month and stalled to keep rain chances in the forecast almost everyday, except for one significant cold frontal passage on the 23rd of September which was able to drop minimum temperatures down into the 50s across the region on the morning of the 24th. No daily temperature or rainfall records were set this month at any of the climate stations. The local climate stations used for this summary include Jacksonville, FL (JAX - history dates back to 1871), Gainesville, FL (GNV - history dates back to 1890), and across southeast Georgia, Alma and St Simons Island, (AMG & SSI - history dates back to 1948).

The forecast for the next 3 months of October, November and December from the Climate Prediction Center (CPC) is calling for equal chances of above, below or near normal temperatures while the precipitation forecast is calling for greater chances of above normal precipitation values. The greater chances of above normal precipitation through the end of the year is due to the ongoing weak El Nino Event in the Pacific Ocean which generally increases the chances of heavy rainfall events across the southeast U.S. and Florida Peninsula through the late fall and winter months.
